WATCH: Britney Spears’ Vegas Show Proves She’s Ready to Work

Britney Spears’ return to the stage Friday was nothing short of a spectacle. The acrobatic, fiery 90-minute show, Britney: Piece of Me, featured not only the pop icon showcasing her catalogue of No. 1 hits, but also an overexcited Miley Cyrus making out with a backup dancer.

So who cares if Britney doesn’t actually sing during her show? What she gives in pumped-up dance moves and dazzling costume changes is a huge leap forward from her disastrous going-through-the-motions 2007 VMA performance.

Spears will perform 50 shows per year at the Planet Hollywood Resort & Casino in Las Vegas through 2015. Watch the best videos captured from her show:
